<P>PROBLEM TO BE SOLVED: To provide a bone anchoring nail which can be connected with an external stabilization rod or a rod-shaped element and inserted more quickly with a force smaller than a widely known device, while providing fixability as secure as screws. <P>SOLUTION: A bone anchoring nail is provided with: threadless shafts (1,1') having a free end (2); heads (3, 3') opposite to the free end having a substantially U-shaped recess (7) for accommodating the rod (12) or the rod-shaped element; a longitudinal bore (4) extending through the shaft and opening towards at least the heads (3, 3') or the free end (2), and a plurality of openings (5) extending through the wall face of the shaft and communicating to the bore (4). The outer surface of the shafts (1, 1') is coated or polished to enhance slidability to facilitate insertion of a nail into the bone. <P>COPYRIGHT: (C)2013,JPO&INPIT |
